✔ 最佳答案

base唔一定係alkali...
只要係可以neutralize左acid既都可以係base...
所以嚴格來講...alkali只係base既其中一部分...
for ex.
NaOH+HCl=NaCl+H2O
CaO+2HCl=CaCl2+H2O

Base is 'opposite' to acid.

Its pH value > 7

e.g. sodium/potassium hydroxide (NaOH, KOH), etc.

base=鹼性(sodium hydroxide solution,potassium hydroxide)

acidic=酸性(citric acid , hydrochloric acid , sulphuric acid)
